Aircraft_hijacking Aircraft hijacking (also known as skyjacking and sky jacking) is the unlawful seizure of an aircraft either by an individual or by a group. In most cases, the pilot is forced to fly according to the orders of the hijackers. However, there have been cases where the hijackers have flown the aircraft themselves.Unlike the hijacking of land vehicles or ships, skyjacking is usually not perpetrated in order to rob the cargo.
